Counties with the Highest Medicare Advantage Market Penetration

Exhibit 1

According to April 2020 CMS Data, Miami-Dade county in Florida and Monroe county in NY lead the nation by Medicare Advantage penetration. About two-thirds of the Medicare eligible population living in those counties have a MA plan – over twice the national average of 36%. This represents an impressive growth of MA plans that leads the nation. Additionally, it is not only counties with relatively higher populations experiencing a growth of MA plan enrollments amongst eligible beneficiaries – Meeker and McLeod County in Minnesota also see approximately 3 out of 5 consumers go with MA plans.
